It's all about Methane: Comprehensive spatial species and temperature profiles are reported for an oxidative coupling of methane (OCM) fixed-bed reactor. Profiles presented at different CH4/O2 ratios provide important new information that is necessary for the refinement and rigorous validation of detailed chemical kinetic mechanisms for this process. The data reveal new insights into the kinetics and mechanism of the OCM reaction.
